Abstract

The innovation concerns a wood harvesting method and a harvester head. The method is used to harvest all sizes of trees without taking the harvester to the site more than once. The method consists of placing the harvester head against the first tree, closing all grapples around the tree, cutting the tree with the cutting device, lifting the cut tree a little by holding it with the grapples fastened to the telescopic boom and using the stroke cylinder to move the telescopic boom in relation to the main body, moving to the next tree, opening the rigid grapples and holding the first tree in an upright position with the articulated grapples, closing the rigid grapples around the tree, opening the articulated grapples, so that their turning tips slide away from between the trees, closing the articulated grapples around all the trees, cutting the tree with the cutting device, and continuing the work in the above described order by collecting more trees and cutting them, until the grapples are full. The harvester head includes the main body, telescopic boom moving in relation to the main body, a device for cutting trees and several pairs of grapples for holding the trees, with at least one pair of grapples equipped with articulated grapples.
